Brendan Boor, Assistant Professor of Civil Engineering, who carries out bed research, also found that bed dust in the air triggers allergies – causing watery eyes, sneezing, coughs and asthma. He has recommended ways to limit our exposure to these unsavoury allergens:

Firstly, he suggests vacuuming your mattress regularly – weekly, or even daily. He also recommends doing away with carpets and washing floors. Using allergen-proof bed covers, he says, can reduce the risk of getting allergies. In addition, washing bedding and pillows frequently can help, as can a portable air cleaner placed near the bed.

If you do as Brendan Boor suggests, you will breathe in cleaner air as you sleep… or will you? Is it really safe for you to go back in your bed…?
